OIL-BURNER.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed February 28, 1908. Serial No. $18,187.

To all whom it may concern:

lie it known that. I, EDWARD W. THOMAS, a c1t1zen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and-useful Improvements inOil-Burn" ers; and I do declare the following to, be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompany- -ing drawings, and to the characters of referencemarked thereon, which form a part of this application. i

- This invention relates to improvements in oil burners and particularlyto that class used in connection with stationary or locomotive fireboxes of all kinds, the object of the invention being to produce aburner having a fan shaped discharge or burning nozzle, whereby the heatwill be evenly and effectively distributed throughout the fire boxwithout the annoyance of expansion and contraction consequent uponuneven distribution, so often now encountered, thus doing away with thenecessity of brick arches as now used; also to produce a burner justablewhich will economize fuel and prevent the accumulation of carbon orother deleterious matter in the ash pan; also to provide a simple andinexpensive burner for the purpose. These objects I accomplish by meansof a main casing having oil and steam inlets and provided with asubstantially fan shaped outlet for each, there being a fan shapedburner plate or lip onto which the oil flows, the steam sweeping ordischarging directly across the surface of said plate, thus thoroughlyatomizing and mixing with the oil, as is necessary to produce perfectcombustion; also by such other and further construction as will appearby a perusal of the following specifieatmn and claims.

Inthe drawings similar characters of reference indicate correspondingparts in the several views:

Figure l is a perspective view of the complete burner. Fig. 2 is alongitudinal section of the same. Fig. 3 is a perspective view of theburner lip or plate showing an adjustable gasket or guide plate thereon.Fig. 4 is a view similar to Fig. 3 showing fixed raised gasket or guideplates on the same. Fig. 5 is a top plan View of the adguide plates.Referring now more particularly to the characters of reference on thedrawings 1 designates the main casing of the device provided with an oilinlet 2 and a steam inlet 3, the inlet 2 reducing to an oblong passageway 4 flaring into a substantially fan shaped discharge nozzle 5.Similarly the inlet 3 reduces to an oblong passage way 6, over the mouthof which is suitably secured a vertical plate 7 provided with anoutwardly extending flat fan shapedburner plate or lip 8, thesame beingspaced but a minute distance from the roof of the passage 6 and held insuch spaced position by means of fixed or adjustable guide plates orgaskets 9, the said member 8 being beveled downward at its inner end asat 10 to permit the steam to readily pass into the space between saidplate and the roof of said passage (3 as shown. The gaskets 9 areconstructed to conform to the fan shape of the lip 8 and the outer edgesof the members 5 and 8 are provided with a curve to carry out the schemeof the fan shape of those members and thus aid in the operation thereof.The casing is formed with projecting lugs 11 forming side walls orguides at each end of the plate 8, the members 9 fitting snugly againstlugs 11, since the bottoms of said lugs are formed flush with the roofof the passage 6.

' 12 is a centrally orificed lug on the rear of the casing 1 for theurpose of securing the burner to the rear p ate of the mud ring of thefire box.

In practice the oil is fed into the inlet 2 and flows through thepassage way 4 out the discharge nozzle 5 onto the plate 'or lip 8. Thesteam passes into the inlet 3 and passes through the passage way 6 andby reason of the reduced space between the plate 8 and the roof of thepassage 6 it escapes withgreat force through thespace 10 over the plateor lip 8 and thus picks up the oil flowing onto said plate andthoroughly, atomizes and gasifies the same as is required, the flamespreading evenly throughout the fire box in a substantial fan shape byreason of the construction described. This fan shaped effect is of greatimportance, since it throws the flame equally to all arts of the firebox, thus overcoming the di culties set forth in the statement of theobjects of this invention.

The members 9 form lides for the sweep of the steam and oil an may beeither fixed as shown in Fi 4, or adjustable as shown in Fig. 3 for t epurpose of changing the I flame.

I tions from such detail may be resorted to as From the foregoingdescription it will be readily seen that I have produced a burner whichsubstantially fulfils all the objects of the invention as set forthherein.

While this specification sets forth in detail the present and preferredconstruction of my invention, still in practice such deviado not form adeparture from the spirit of the invention.

Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent is '1. An oil burner comprising abody portion having an oil and asteam conduit, such oil-conduitprojecting a greater distance forward than said steam conduit,projecting side lugs on either side of a plate disposed over the mouthof said steam assa e, a horizontal projecting lip projecting forwardfrom said plate and clear of said body and spaced a slight distance fromthe roof of said steam conduit, and gaskets disposed between said lipand said Oll conduit,

I said side lugs.

2. An oil burner comprising a body portion having oil and steamconduits, a lip projectin rward from said steam conduit, gaskets isposedbetween said lip and the roof of said steam conduit, said gaskets beingadjustable longitudinally with respect to said lip, as set forth.

In testimonywhereof I aflix my signature in presence of two witnesses.
